Replace multi-version Node.js installations with targeted single-version approach to reduce image size and eliminate unused binaries. Updates version detection logic to provide three distinct categories: previous LTS, current LTS, and latest stable. Each distribution variant now installs exactly one Node.js version aligned with its maturity level, simplifying builds and creating more predictable environments.
